Description

Technical Field

[0001] The utility model belongs to the technical field of air cooling towers, and in particular relates to an air cooling tower with high heat exchange efficiency. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant, absorbing heat from the system and discharging it into the atmosphere, thereby lowering the air temperature inside the tower and producing recyclable cooling water.

[0003] Among them, the counterflow tower is a common type of cooling tower. Its working principle is: water flows downward from top to bottom, while wind blows upward from bottom to top, which increases the efficiency of heat dissipation. Due to its reasonable heat dissipation structure, it is widely used in the field of heat dissipation technology.

[0004] The heat dissipation performance of a cooling tower mainly depends on the structural design of its internal filling material. Because 70% of the heat exchange in the cooling process of circulating cooling water in the cooling tower is completed in the filling part, the structure of the filling directly affects the heat exchange efficiency of the cooling tower. The filling composed of filling sheets is a key component for cooling water in the cooling tower. When water passes through the filling sheets, the water is dispersed into a very thin water film, which contacts the air with the largest possible surface area to achieve the purpose of sufficient heat exchange. When the cooled water passes through the filling, the larger the surface area formed, the better the cooling effect. At the same time, the smaller the resistance of the filling to the air, and the longer the time the water stops leaking on the filling sheet, the better the cooling effect.

[0005] However, some commonly used fillers still have some defects in strength, surface area, air resistance, and stop leakage time, which makes the cooling effect of the whole tower unsatisfactory, and causes the cooling tower to have problems such as low heat exchange efficiency, poor cooling effect and serious energy waste.

[0006] In order to solve these problems, it is necessary to design a new type of air cooling tower, which aims to improve cooling efficiency and reduce energy consumption by optimizing structural design. Utility Model Content

[0058] A spray assembly 30, wherein the spray assembly 30 is disposed in the cooling reaction chamber 13, and the spray assembly 30 is connected to the water inlet structure 14 and sprays hot water upward;

[0059] A filler 40, wherein the filler 40 is arranged in the height direction between the spray assembly 30 and the air inlet 12; wherein the filler 40 is formed by a plurality of disc-shaped plates 41 arranged in the vertical direction, and all the disc-shaped plates 41 are provided with a plurality of short flow channels 411 that enable gas and liquid to flow freely in the vertical direction;

[0060] as well as

[0061] The water storage tank 50 is disposed at the bottom of the housing 10 and is used to store cooled water.

[0062] Specifically, the air cooling tower with high heat exchange efficiency of the utility model comprises a shell 10, a fan 20, a spray assembly 30, a filler 40 and a water storage tank 50;

[0063] The housing 10 is in the shape of a tower, with an air outlet 11 on the top and multiple air inlets 12 on the side wall to ensure smooth air circulation. The cooling reaction chamber 13 formed in the hollow interior provides space for sufficient contact between hot water and air.

[0064] The fan 20 is provided at the air outlet 11, and is used to discharge the hotter air inside the cooling reaction chamber 13, and introduce the external air into the cooling reaction chamber 13. By adjusting the rotation speed of the fan 20, the flow rate and flow velocity of the air can be controlled, thereby optimizing the heat exchange effect;

[0065] The spray assembly 30 is disposed in the cooling reaction chamber 13 and is connected to the water inlet structure 14 to spray hot water upward. When the hot water falls, it can be evenly sprayed onto the filler 40 to form a large-area water film, thereby increasing the contact area with the air.

[0066] The filler 40 is arranged in the height direction between the spray assembly 30 and the air inlet 12. The filler 40 is composed of a plurality of disc-shaped plates 41 arranged in the vertical direction. Each plate is provided with a plurality of short flow channels 411. This design enables the gas and liquid to flow freely in the vertical direction, greatly improving the heat exchange efficiency.

[0067] The water storage tank 50 is disposed at the bottom of the housing 10 and is used to store cooled water;

[0068] The cooling tower significantly improves the heat exchange efficiency of the air cooling tower and improves the overall cooling effect mainly by optimizing the filler 40 structure, increasing the heat exchange area, and improving the water flow turbulence.

[0069] In another embodiment of the present invention, the outer surfaces of all the disc-shaped plates 41 and the outer surfaces of all the short flow channels 411 are provided with a hydrophilic coating.

[0070] Specifically, in order to enhance the hydrophilicity of the filler 40, a hydrophilic coating is applied to the outer surfaces of all disc-shaped plates 41 and the outer surfaces of the short flow channels 411, which makes it easier for water droplets to disperse and flow on the filler 40. The disc-shaped plates 41 can be made of metal or glass material, and the hydrophilic coating is a fluorocarbon resin coating.

[0071] In another embodiment of the present invention, Figures 1 to 5 As shown, the outer ring side walls of all the disc-shaped plates 41 are in contact with the inner wall of the cooling reaction chamber 13 , and the upper surfaces of all the disc-shaped plates 41 are formed with vertical downward depressions 412 .

[0072] Specifically, the outer side wall of the disc-shaped plate 41 fits tightly against the inner wall of the cooling reaction chamber 13, ensuring that water does not leak from the gap. At the same time, a vertical downward depression 412 is formed on the upper surface of the plate, thereby preventing water from accumulating on the upper surface of the disc-shaped plate 41 and being unable to flow downward.

[0073] In another embodiment of the present invention, Figure 3 , 4 As shown, all the disc-shaped plates 41 are stacked in the vertical direction, and all the short flow channels 411 are closely connected in sequence to form a plurality of long flow channels 413 .

[0074] Specifically, in the vertical direction, the disc-shaped plates 41 are stacked, and the short flow channels 411 therebetween are closely connected to form a plurality of long flow channels 413, thereby increasing the heat exchange time between water flow and air.

[0075] In another embodiment of the present invention, Figure 3 , 4 As shown, all the long flow channels 413 are arranged in a curved shape, and the angles between the medium flow directions of all the long flow channels 413 and the horizontal plane decrease from top to bottom.

[0076] Specifically, all long flow channels 413 are arranged in a curved shape, and the angle between the flow direction of the medium and the horizontal plane decreases from top to bottom. This design can ensure that the water flow constantly changes direction during the flow, thereby increasing the contact area and contact time with the air.

[0077] In another embodiment of the present invention, Figure 3 , 5 As shown, all the disc-shaped plates 41 are arranged at equal intervals in the vertical direction, and the projections of the short flow channels 411 on any two adjacent disc-shaped plates 41 on the horizontal plane do not overlap.

[0078] Specifically, in order to ensure uniform distribution of water flow and prevent blockage, disc-shaped plates 41 are designed to be arranged at equal intervals. The projections of the short flow channels 411 on any two adjacent plates on the horizontal plane do not overlap, which allows the water flow to be dispersed to different areas when passing through, avoiding the water flow from falling rapidly directly in the vertical direction, thereby increasing the contact area and contact time with the air.

[0079] In another embodiment of the present invention, Figure 3 , 5 As shown, the projections of all the short flow channels 411 in the lateral direction are arranged in an inclined shape.

[0080] Specifically, the projections of the short flow channels 411 in the lateral direction are all arranged in an inclined shape, which is also helpful to improve the fluidity and dispersion of the water flow, and can also increase the contact time between the water flow and the air.

[0081] In another embodiment of the present invention, Figure 2 As shown, the spray assembly 30 includes:

[0082] A spray pipe 31, wherein the spray pipe 31 is connected to the water inlet structure 14;

[0083] A spray head 32, wherein the spray head 32 is configured in plurality, and each of the spray heads 32 is connected to the spray pipe 31;

[0084] A control valve is provided on the water inlet structure 14 .

[0085] Specifically, a control valve is also provided on the water inlet structure 14 for controlling the flow and pressure of hot water.

[0086] In another embodiment of the present invention, Figure 2 As shown, each of the spray heads 32 is connected to the spray pipe 31 by a tight fit, and the spraying angle of each of the spray heads 32 can be adjusted.

[0087] Specifically, the spray head 32 and the spray pipe 31 are connected by a tight fit, which ensures the firmness and sealing of the connection. At the same time, the spraying angle of the spray head 32 can also be adjusted, which enables the operator to adjust the spraying range and intensity according to actual conditions.

[0088] In another embodiment of the present invention, Figure 1 As shown, the water tank 50 is provided with a water level sensor for real-time monitoring of the water level in the water tank 50 .

[0089] Specifically, in order to monitor the water level in the water tank 50 in real time, a water level sensor is installed in the water tank 50. The sensor can transmit the water level information to the control system in real time. Once the water level is too low or too high, the control system will automatically adjust the working status of the spray assembly 30 and the water inlet structure 14 to ensure the stable operation of the cooling tower.

[0090] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
